Focal length tool

I drew this focal length tool in TurboCAD to work on my LightObjects.com laser head.

At some point I'll convert it to 3D (unless somebody beats me to it) so I can print one.

Enjoy!

Andy

Andy,

Is this what you're looking for?

BTW, I'm not sure what happed with your drawings but the scale was off and several of the lines didn't intersect properly.

Cheers,
Brian

p.s. I use a simple laser cut "square" to set the focus on my laser.

It was a quick sketch, Brian. I saw that there were non-intersections on the right side but just wanted to get the idea out, not have it perfected.

I have to install a tool to view STL, so I can't answer if this is what I'm looking for.

One of the guys had Solid Works on his machine and was able to open it. That's exactly what I wanted, so I asked the 3D printer guy to make me one next time he's making stuff.

Thanks! Now I need to make it 3D for myself in TurboCAD. The curse of only working in 2D drawings for 40+ years is that you don't have a problem seeing the 3D object just from the 2D drawings.

The important part of a tool like this is to be able to see when the part touches the gauge. Mine tilts so the movement is about doubled. When I need something precise (not very often) I can arrach a 'flag' to it.

With mills we use a touch off gauge. They usually have a dial gauge, or light to show when the bit contacts. I don't think a laser usually needs it that accurate. The pad is often spring loaded incase you jog to far. One of these could be printed to size, and add an indicator.

I'll take a picture if I can find the darn thing I only use it about once a year.

Here is a pic. Held on by magnets. I tape one end so it tilts as it meets the target. For more sensitivity a piece of wire attached adds some leverage.

Thanks. I think I'll stick with what I got, at least until I try it.

This has to be the coolest tool. I just haven't figured out what my first real project for it will be.

What software do you use for running the laser?

corel or cad
the advantage of an established mfg is that they provide a std interface. industrial one use g code, smaller ones are configured as a printer.

Yeah, I knew that going in, and the software that runs it is pretty good and getting better. I only use it for the printing; my real work I do in TurboCAD.

I think I've found some good ways to improve my cut files.

So does the supplied software require gcode to cut from or will it take other types of files?

It supports these:

AI, DXF, PLT, DST, DSB, BMP, GIF, JPG, PNG, MNG, ICO CUR, TIF, TGA, PCX, JBG, JP2, JPC, PGX, RAS, PNM, SKA, RAW

So far I've only played with DXF and TIFF files.

OK, so any drawing software is compatible.
